OCDs for mulitple charge controllers
Do I need to have a complete separate set of over current devices or disconnects for multiple charge controllers? As an example, I am intending to install 2000 watts of PV for a customer, and add a second Outback charge controller to their existing set up. I know I need OCDs or disconnects for the PV in and PV out, but do I need an additional GFCI? Any thoughts would be appreciated.
